Sectorised Radio Channel Characterisation for Ultra Wideband Body-centric Wireless Communications

The paper aims to investigate optimum locations for ultra wideband (UWB) nodes placement on the body for reliable body-centric wireless communications. The performance of UWB radio propagation links is experimentally investigated by considering communications between body-worn base units and off-body access points. Radio channel parameters are derived and analysed for different sectors of the human body. Results suggest that lowest path loss exponent is obtained for lower parts of legs
